- Homework Statement
- given X an Y uniformly distributed on [0,1] independent find the density of S=X+Y
- Relevant Equations
- Fs(Z)=P[X+Y<=Z]
i did not get how the professor came to such result. In particular:
in order to evaluate
P[x+y<=z] solved a double integral of the joint density. What i am not getting is did i choose the extreme of integration in order to get as result ##\frac {z^2} {2}##
